Abstract

An elongate construction element ( 1; 19, 20 ) including a first elongate profile ( 2 ) with a first section ( 2 ′) located in a first plane and a second section ( 2 ″) located in a second plane different from the first plane, a second elongate profile ( 3 ) with a first section ( 3 ′) located in a first plane and a second section ( 3 ″) located in a second plane different from the first plane, and at least one third profile ( 4; 4′, 4″, 4′″, 14 ). The respective first sections ( 2′, 3 ′) of the first and the second profile are located in essentially the same plane, and the third profile ( 4; 4′, 4″, 4′″, 14 ) constitutes a web which is fixed to and interconnects the first sections along at least a part of the extent of the construction element. The invention also relates to a frame for a vehicle, which frame comprises at least a pair of such construction elements.

       10 . The construction element as recited in  claim 8 , wherein the first and the second profile have different dimensions.  
   
   
       11 . The construction element as recited in  claim 8 , wherein the distance between a delimiting surface of the web running along a respective first section and the intersection lines of the first and second sections for the respective profile are essentially constant.  
   
   
       12 . The construction element as recited in  claim 8 , wherein the first profile ( 2 ) is bent so that the distance between the intersection lines of the first and second sections ( 2 ′,  2 ″;  3 ′,  3 ″) for the respective profile ( 2 ,  3 ) converges along at least a part ( 2   b ) of the extent of the construction element.  
   
   
       13 . The construction element as recited in  claim 8 , wherein the third profile consists of a plate ( 4 ;  14 ;  34   a ,  34   b ,  35   a ,  35   b ,  36   a ,  36   b ) which connects the two construction elements.  
   
   
       14 . The construction element as recited in  claim 8 , wherein the third profile consists of an end plate ( 37   a ,  37   b ,  38   a ,  38   b ,  39   a ,  39   b ) forming part of a crossbeam which connects the two construction elements.  
   
   
       15 . The construction element as recited in  claim 1 , wherein the web is arranged to overlap the first sections.  
   
   
       16 .
